The final episode of the final series shows us Miller's Court, No13 and Mary Kelly in situ.
I've created a short blog post with some screen grabs from that episode. Mary Kelly's body was shown for a split second and it's very graphic (as you'd expect). Not sure if it's TOO graphic if that's possible!

So click the link to view the blog post but I place a warning on this to be prepared for a couple of nasty images.
